Snow 2.0 ---> random feathers (can't get it to work)

1

Basically my idea is to have falling feathers rather than snow. I’ve sucessfully done the tut (snow v2.0) and am using a feather image in place of the snow, this works fine.
However since i have different types of feathers, i wish to have it rain several types of feathers at once.
I tried adding another duplicateMovieClip into the loop

k = 0;
feathers = 20;
do {
		duplicateMovieClip(feather_1, "feather1"+k, k);
		duplicateMovieClip(ffeather_2, "feather2"+k, k);
		duplicateMovieClip(ffeather_3, "feather3"+k, k);
	k++;
} while (k != feathers);

This didn’t work, it only rained feather3.

then i tried a random selection (wats the dif between random() and maths.random() ??)

k = 0;
 feathers = 20;
 do {
		rannum = random(4)
 		duplicateMovieClip(feather_rannum, "feather"+k, k);
 	k++;
 } while (k != feathers);

this didn’t work either, only one of each type fell >.<

mayb another way, or i am doing it the wrong way?

Thanks for reading; srry still fresh to actionscript ^^
